Description

图片管理方法及设备、图片同步方法及设备 技术领域
本公开涉及图片管理方法和设备、以及图片同步方法和设备。
背景技术
随着处理器、存储芯片、摄像头等硬件的小型化，诸如手机、Pad等终端设备除了作为日常通讯工具外，正在越来越多地承担起声音、图像等信息的采集功能和存储功能。例如，据统计，如今每天通过手机、Pad等终端设备拍摄产生的图片已经超过了十亿的量级。因此，如何能帮助用户高效地、智能地组织管理图片数据成为了一个非常具有意义和发展前景的方向。
目前，市场上已有不少可以应用于终端设备的、用于组织管理图片数据的产品，如各类手机相册应用。在这些已有的手机相册应用中，大部分是按照拍摄时间或拍摄地点对图片进行分类管理的，而并不对图片内容进行分析并加以利用。这样在用户想要查找自己以前拍摄过的某张图片或从别处导入的某张图片时，只能通过拍摄时间或地点来进行查找，这在用户不确定图片的拍摄时间或地点的情况下会很不方便。还有些手机相册应用则通过图片标签(tag)来对图片进行分类管理。然而，由于缺少基于图片内容的智能生成工具，目前图片标签只能由人工产生，因此无法处理大批量的图片数据。另一方面，部分现有的手机相册应用仅在本地终端设备上存储图片数据，这导致用户只要换了一个终端设备就会无法访问其拥有的另一终端设备上的图片数据。考虑到这一情况，有些手机相册应用产品利用云平台对图片数据进行同步和备份，从而使得能够在用户拥有的多个终端设备上共享图片数据。然而，云平台一旦出现了安全漏洞，则用户的全部图片数据可能会被窃取或泄露。
发明内容
鉴于以上问题而提出了本公开。具体而言，本公开的目的在于提出一种图片管理技术，通过该技术，可以采用自动分析图片内容所产生的标签对图片分类归档、建立索引，从而使得用户对图片的查询与管理可以更加精确和 人性化。本公开的目的还在于提出一种图片同步技术，通过该技术，可以在多个客户端设备之间共享图片数据，同时能够确保图片数据的安全性。
根据本公开的一个方面，提供了一种图片管理方法，应用于客户端设备，包括：接收服务端设备基于接收到的原始图片特征进行图像分析而生成的图片标签，所述原始图片特征是原始图片本身或原始图片参数；根据所述图片标签对所述原始图片特征所表征的原始图片进行分类归档。
可选的，所述原始图片存储在应用所述图片管理方法的客户端设备本地。并且，在所述原始图片特征是原始图片参数的情况下，所述图片管理方法还包括：将所述原始图片发送至所述服务端设备。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行 清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1示意性地示出了应用根据本公开实施例的图片管理技术及图片同步技术的一种示例场景。如图1所示，该示例场景中包括终端设备101、102以及服务端设备103，其中终端设备101、102与服务端设备103经由网络110互联。根据本公开实施例的图片管理技术可以应用于该终端设备101、102及服务端设备103，以对其中存储的图片进行组织和管理；另一方面，终端设备101和102可以应用本公开实施例的图片同步技术、经由服务端设备103来进行相互之间的图片备份和同步。尽管图1中示出服务端设备103为单个设备，其实际上可以是多个设备的集合。
图2示出了根据本公开实施例的图片管理方法200的流程图。该图片管理方法200可应用于客户端设备，例如图1中所示的终端设备101或102。下面将参考图2来描述根据本实施例的图片管理方法。
如图2所示，在步骤S201，接收服务端设备基于接收到的原始图片特征进行图像分析而生成的图片标签。
参考图1，在该步骤中，例如图1中所示的终端设备101或102接收来自于服务端设备103的图片标签，其中该图片标签是服务端设备103对所接收到的原始图片特征进行图像分析而生成的。
原始图片特征是原始图片本身或者是原始图片参数。原始图片参数是与原始图片有关的、并且可以用来进行图像分析的任何适当的参数，例如其可以是需要组织管理的原始图片的压缩编码、或原始图片的图像特征、或其组合。原始图片的图像特征是现有的图像处理领域中可以用来对图像进行分析的特征，例如梯度直方图(HOG)、尺度不变特征变换(SIFT)、深度网络的特征层等。
针对接收到的原始图片特征，服务端设备对其进行各种适当的图像分析以生成反映图片内容的图片标签。图3例示了服务端设备对于原始图片特征进行图像分析以生成反映图片内容的图片标签的一种可能的处理情形。
如图3所示，服务端设备对原始图片特征进行包括(但不限于)人脸检测/识别、文字检测/识别、物体检测/识别、场景识别的各种图像处理。人脸 检测/识别用于检测图片中是否包含人脸，并在检测到人脸时对人脸进行识别，以将识别出的一个或多个具体的人物作为图片标签；文字检测/识别用于检测图片中是否出现文字(如书本、街店招牌等)，并在检测到文字时对文字进行识别，以将识别出的一个或多个具体文字作为图片标签；物体检测/识别用于检测图片中是否出现物体(如汽车，自行车，房屋等)，并在检测到物体时对物体进行识别，以将识别出的一个或多个具体物体作为图片标签；场景识别用于确定图片的场景模式(如室内、室外)，并将确定的场景模式作为图片标签。上述基于原始图片特征、即基于原始图片本身或基于原始图片参数的人脸检测/识别、文字检测/识别、物体检测/识别、场景识别可以采用本领域中任何已有的图像处理技术来进行，此处不进行详细描述。通过上述图像处理，能够自动且智能的分析出原始图片的内容，并由此生成反映图片内容的图片标签。能够理解，上述各种图像处理仅仅是示例，而并非是对本公开的限制，本领域技术人员也可以应用其他适当的图像处理方式，以获得能够反映图片内容的图片标签。
在步骤S202，根据所述图片标签对所述原始图片特征所表征的原始图片进行分类归档。
如前所述，图片标签是基于原始图片特征而生成，而原始图片特征则是能够表征原始图片的压缩编码和/或图像特征、或原始图片本身。因此，在该步骤中，在接收到反映图片内容的图片标签后，客户端设备可以基于该图片标签对原始图片特征所表征的原始图片进行分类归档、索引建立等各种图片管理。
以上已经结合图2对根据本公开实施例的图片管理方法200的总体处理进行了描述。根据该图片管理方法200，客户端设备能够基于图片内容对原始图片进行分类归档、索引建立等，进而使得用户可以根据图片内容来查询图片，从而使得查询更加高效和人性化。另一方面，根据该图片管理方法200，图片标签并不是在客户端设备本地生成，而是由服务端设备通过图像处理来生成，因此客户端设备不需要耗费大量的资源进行大量的数据计算。
上述图片管理方法200既可以应用于在本地初始存储有原始图片的客户端设备，也可以应用于在本地初始未存储有原始图片的客户端设备。下面将分别对这两种情形做进一步的描述。
作为一种示例，在本地初始存储有原始图片的客户端设备A(以下简称为“客户端设备A”)上应用该图片管理方法200时，在原始图片特征是原始图片参数的情况下，该方法200可以进一步包括：客户端设备A将原始图片发送至服务端设备。当然，在原始图片特征是原始图片本身的情况下，则不需要再执行该原始图片发送步骤。而在接收到服务端设备生成的图片标签后，该客户端设备A根据该图片标签对其本地存储的原始图片进行分类归档。另外，在该情形中，服务端设备所接收到的原始图片特征也来自于该客户端设备A。与此相对应，作为一种示例，在本地初始未存储有原始图片的客户端设备(以下简称为“客户端设备B”)上应用该图片管理方法200时，该方法200可以进一步包括：在根据图片标签对原始图片分类归档之前，客户端设备B接收服务端设备从不同于该客户端设备B的另一客户端设备A接收到的原始图片。由此，在接收到服务端设备生成的图片标签后，该客户端设备B可以根据该图片标签对其从该服务端设备下载的原始图片进行分类归档。
作为另一种示例，当在客户端设备A上应用该图片管理方法200、并且原始图片特征是原始图片参数时，该方法200可以进一步包括：生成与客户端设备A绑定的唯一密钥；利用该唯一密钥对所述原始图片进行加密；将加密的原始图片发送至服务端设备。根据该示例，客户端设备A并不将原始图片发送至服务端设备，而是发送原始图片参数，并且生成密钥并将利用该密钥加密的原始图片发送至服务端设备，因此在服务端设备端无法得到原始图片，由此能够防止图片数据通过网络外泄，保证图片数据的安全。与此相对应，作为另一种示例，当在客户端设备B上应用该图片管理方法200、并且原始图片特征是原始图片参数时，该方法200可以进一步包括：在根据图片标签对原始图片分类归档之前，客户端设备B接收服务端设备从不同于该客户端设备B的另一客户端设备A接收的加密的原始图片；从不同于服务端设备的另一设备接收对原始图片进行加密的唯一密钥；利用该唯一密钥对所述加密后的原始图片进行解密以得到原始图片。其中，所述不同于服务端设备的另一设备可以是生成密钥的客户端设备A，在此情况下客户端设备B从该客户端设备A接收所述唯一密钥；或者，所述不同于服务端设备的另一设备可以是生成密钥的终端设备A预先将密钥发送到其中的另一服务端设备，在此情况下客户端设备B从该另一服务端设备接收所述唯一密钥。根据该示例， 原始图片未被发送到服务端设备，相应地客户端设备B从服务端设备下载的也不是原始图片，而是加密的原始图片，其只有在从不同于服务端设备的另一设备获得密钥之后，才能利用该密钥进行解密以恢复原始图片，进而根据图片标签对恢复的原始图片进行分类归档。由此能够防止未授权设备获取原始图片，从而保证了图片数据的安全。
图4示出了根据本公开另一个实施例的图片管理方法400的流程图。该图片管理方法400可应用于服务端设备，例如图1中所示的服务端设备103。下面将参考图4来描述根据本实施例的图片管理方法。
如图4所示，在步骤S401，服务端设备接收原始图片特征和加密的原始图片。
在该步骤中，服务端设备接收需要组织管理的原始图片的图片特征，以及加密的原始图片。作为示例，原始图片特征和加密的原始图片可以来自于存储有大量的原始图片、并希望在服务端设备上进行图片备份的客户端设备。
如前所述，原始图片特征是原始图片本身或者是原始图片参数。原始图片参数是与原始图片有关的、并且可以用来进行图像分析的任何适当的参数，例如其可以是需要组织管理的原始图片的压缩编码、或原始图片的图像特征、或其组合。原始图片的图像特征是现有的图像处理领域中可以用来对图像进行分析的特征，例如梯度直方图(HOG)、尺度不变特征变换(SIFT)、深度网络的特征层等。
在步骤S402，对接收到的原始图片特征进行图像分析以生成图片标签，并在生成所述图片标签后丢弃该原始图片特征。
针对接收到的原始图片特征，服务端设备对其进行诸如人脸检测和识别、文字检测和识别、物体检测和识别、图片场景识别等各种适当的图像分析以生成反映图片内容的图片标签。该步骤中的具体处理可以采用上文中结合图3所描述的处理方式，此处不再赘述。
在生成所述图片标签后，服务端设备主动丢弃该原始图片特征。这样，可以保证服务端设备处不会保存原始图片，从而可以避免原始图片在服务端设备处可能的泄露及由此导致的数据安全问题。
在步骤S403，根据所述图片标签对所述原始图片特征所表征的加密的原始图片分类归档。
如前所述，图片标签是基于原始图片特征而生成，而原始图片特征则是能够表征原始图片的压缩编码和/或图像特征、或原始图片本身。因此，在该步骤中，在生成反映图片内容的图片标签后，可以基于该图片标签对接收到的加密的原始图片进行分类归档、索引建立等各种图片管理。
以上已经结合图4对根据本公开实施例的图片管理方法400进行了描述。根据该图片管理方法400，服务端设备基于图片内容对图片进行分类归档、索引建立等，由此可以根据图片内容来查询图片，从而使得查询更加高效和人性化。另一方面，服务端设备在利用原始图片特征生成图片标签后主动丢弃该原始图片特征，从而避免了原始图片在服务端设备处可能的数据泄露，相应地，服务端设备对加密的原始图片而不是原始图片本身进行分类归档。因此在服务端设备处能够在根据图片内容管理图片的同时，保证图片数据的安全。
需要说明的是，在以上结合图4描述的图片管理方法中，服务端设备分类归档是加密的原始图片而不是原始图片本身，实际上，在不要求图片数据的安全性时，作为一种替换，服务端设备也可以对原始图片本身、而不是对加密的原始图片进行分类归档。即，在上述步骤S401中服务端设备接收原始图片，在步骤S402中服务端设备在生成图片标签后不丢弃所述原始图片，并且相应地在步骤S403中根据图片标签对原始图片分类归档。按照该替换实现方式，服务端设备仍然可以基于图片内容对图片进行分类归档、索引建立等，从而使得可以根据图片内容来查询图片。
下面将结合图5至图7，描述应用根据本公开实施例的上述图片管理方法的几个具体示例。
图5示出了应用根据本公开实施例的图片管理方法的一个具体示例。在该示例中，不考虑图片数据的网络安全性。如图5所示，在该示例中，具有两个终端设备101，102及服务端设备103。此处，为了便于说明，假设要进行图片管理的原始图片初始存储在终端设备101。
如图5中所示，在步骤S501，终端设备101发送原始图片至服务端设备103；在步骤S502，服务端设备103接收该原始图片；在步骤S503，服务端设备103对接收到的原始图片进行图像分析以生成图片标签；在步骤S504，服务端设备103根据该图片标签对所述原始图片进行分类归档；在步骤S505， 终端设备101从服务端设备103接收所述图片标签；在步骤S506，终端设备101根据所述图片标签对原始图片进行分类归档；在步骤S507，终端设备102从服务端设备103接收所述原始图片和图片标签；在步骤S508，终端设备102根据所述图片标签对接收到的原始图片进行分类归档。
上述各步骤的具体处理与上文中结合图2和图4描述的图片管理方法中的对应步骤的处理相同，此处不再详细描述。在图5所示的示例中，在不同的终端设备101和102上实现了基于图片内容对图片的智能分类归档，并且通过服务端设备103实现了图片数据的备份和共享。
需要说明的是，在图5中将服务端设备103示出为单个设备，可选的，其可以是多个服务端设备的集合，其中的每个服务端设备执行服务端的部分操作。例如，作为示例，所述服务端设备103可以包括用于进行图像分析以生成图片标签的服务端设备103a(未示出)，和用于存储图片数据及图片标签并进行图片的分类归档的服务端设备103b(未示出)。能够理解，按照这一示例，上述步骤S502、S503由服务端设备103a执行，而步骤S504则由服务端设备103b执行；并且在步骤S503和S504之间进一步包括步骤：服务端设备103a将原始图片和生成的图片标签发送到服务端设备103b。
图6示出了应用根据本公开实施例的图片管理方法的另一个具体示例。在该示例中，考虑图片数据的网络安全性。如图6所示，在该示例中，具有两个终端设备101，102以及服务端设备103。此处，为了便于说明，假设要进行图片管理的原始图片初始存储在终端设备101。
如图6中所示，在步骤S601，终端设备101生成与其绑定的唯一密钥，并利用该唯一密钥对原始图片进行加密以生成对应的加密的原始图片；在步骤S602，终端设备101将原始图片特征和加密的原始图片发送至服务端设备103；在步骤S603，服务端设备103接收该原始图片特征和加密的原始图片；在步骤S604，服务端设备103对接收到的原始图片特征进行图像分析以生成图片标签，并在生成图片标签后丢弃所述原始图片特征；在步骤S605，服务端设备103根据该图片标签对所述加密的原始图片进行分类归档；在步骤S606，终端设备101从服务端设备103接收所述图片标签；在步骤S607，终端设备101根据所述图片标签对原始图片进行分类归档；在步骤S608，终端设备102从服务端设备103下载所述加密的原始图片及图片标签；在步骤 S609，终端设备102从终端设备101接收加密原始图片时所采用的唯一密钥；在步骤S610，终端设备102利用所述唯一密钥对加密的原始图片进行解密，以得到原始图片；在步骤S611，终端设备102根据所述图片标签对接收到的原始图片进行分类归档。
上述各步骤的具体处理与上文中结合图2和图4描述的图片管理方法中的对应步骤的处理相同，此处不再详细描述。在图6所示的示例中，在不同的终端设备101和102上实现了基于图片内容对图片的智能分类归档，并且通过服务端设备103实现了图片数据的备份和共享；同时，由于必须同时获得加密图片和密钥才能恢复原始图片而密钥并不发送至服务端设备103，而且服务端设备在生成图片标签后又主动丢弃原始图片特征，因此无法从服务端设备获得原始图片，从而确保了图片数据的安全性。
需要说明的是，在图6中将服务端设备103示出为单个设备，可选的，其可以是多个服务端设备的集合，其中的每个服务端设备执行服务端的部分操作。例如，作为示例，所述服务端设备103可以包括用于进行图像分析以生成图片标签的服务端设备103a，和用于存储图片数据及图片标签并进行图片的分类归档的服务端设备103b。
在服务端设备103包括上述服务端设备103a和服务端设备103b的情况下，作为另一个示例，上述步骤S603、S604由服务端设备103a执行，而步骤S605则由服务端设备103b执行，并且在步骤S604和S605之间进一步包括步骤：服务端设备103a将加密的原始图片和生成的图片标签发送到服务端设备103b。作为另一个示例，上述步骤S603由服务端设备103a和103b共同执行，其中服务端设备103a接收原始图片特征，服务端设备103b接收加密的原始图片，步骤S604由服务端设备103a执行，而步骤S605则由服务端设备103b执行，并且在步骤S604和S605之间进一步包括步骤：服务端设备103a将生成的图片标签发送到服务端设备103b。作为另一个示例，上述步骤S603由服务端设备103a和103b共同执行，其中服务端设备103a接收原始图片特征，服务端设备103b接收加密的原始图片，步骤S604由服务端设备103a执行，而步骤S605则由服务端设备103b执行，并且在步骤S604和S605之间进一步包括步骤：服务端设备103a将生成的图片标签发送到终端设备101，该终端设备101将该图片标签发送到服务端设备103b。
图7示出了应用根据本公开实施例的图片管理方法的另一个具体示例。在该示例中，考虑图片数据的网络安全性。如图7所示，在该示例中，具有两个终端设备101，102以及两个服务端设备103，104。此处，为了便于说明，假设要进行图片管理的原始图片初始存储在终端设备101。
图7所示的具体示例中的各步骤与图6所示的具体示例中的各步骤基本相同，其区别仅在于：在与图6中的步骤S609对应的步骤S609’中，终端设备102从另一服务端设备104接收加密原始图片时所采用的唯一密钥，并且在该步骤S609’之前，生成密钥的终端设备101预先将密钥发送到该另一服务端设备104上。
在图7所示的示例中，在不同的终端设备101和102上实现了基于图片内容对图片的智能分类归档，并且通过服务端设备103实现了图片数据的备份和共享；同时，由于必须同时获得加密图片和密钥才能恢复原始图片而密钥并不发送至服务端设备103，因此无法从服务端设备获得原始图片，从而确保了图片数据的安全性。
以上已经结合附图对根据本公开实施例的图片管理方法及其示例应用进行了详细描述。此外，本公开事实上还提供了一种图片同步方法，下面对该图片同步方法进行描述
图8示出了根据本公开实施例的图片同步方法800的流程图。该图片同步方法800可应用于客户端设备，例如图1中所示的终端设备101或102。下面将参考图1和图8来描述根据本实施例的图片同步方法。为了便于说明，在本实施例中，以在终端设备102上应用该图片同步方法800、从而同步得到终端设备101中的原始图片为例进行说明，反之亦然。
如图8所示，在步骤S801，从服务端设备下载由另一客户端设备生成并上传至该服务端设备的加密的原始图片。
对于如图1所示的示例情形，在该步骤中，终端设备102从服务端设备103下载加密的原始图片，所述加密的原始图片是由终端设备101生成并上传至服务端设备103的。其中，终端设备101可以例如如前所述通过如下处理生成加密的原始图片并上传至服务端设备：生成与终端设备101绑定的唯一密钥；利用该唯一密钥对原始图片进行加密；将加密的原始图片发送至服务端设备。
在步骤S802，从不同于服务端设备的另一设备接收加密原始图片时所采用的唯一密钥。
仍然以图1所示的示例情形为例，在该步骤中，终端设备102从不同于服务端设备103的另一设备接收加密原始图片所采用的唯一密钥。
作为示例，所述另一设备可以是生成所述密钥的终端设备101。则在该示例中，终端设备102通过例如P2P传输、蓝牙等无备份网络传输方式从终端设备101接收所述密钥。
作为另一示例，所述另一设备是生成密钥的终端设备101预先将密钥发送到其中的另一服务端设备104。则在该示例中，终端设备102在该另一服务端设备104上进行身份验证，以确定其是否有权限获取所述密钥，并且当该终端设备102通过身份验证后，从该另一服务端104设备得到所述密钥。
在步骤S803，利用所述唯一密钥对加密的原始图片进行解密，以得到原始图片。
在通过上述步骤S801和S802分别从服务端设备103及另一设备获得加密的原始图片和密钥之后，终端设备102利用该密钥对加密的原始图片进行解密，从而获得原始图片。
根据以上结合图1和图8描述的图片同步方法800，加密的图片和密钥由两个相互独立的设备管理，因而要进行同步的终端设备必须从这两个相互独立的设备同时获得这两者才能恢复原始图片，进而实现与存储有所述原始图片的终端设备的图片数据同步。由此，能够经由服务端实现多个终端设备之间的图片共享，同时能够确保图片数据的安全性。
以上已经结合附图描述了根据本公开实施例的图片管理方法和图片同步方法。应该理解，本公开中的步骤流程图以及以上方法描述仅作为例示性的例子并且不意图要求或暗示必须按照给出的顺序进行各个实施例的步骤，某些步骤可以并行、彼此独立或按照其他适当的顺序执行。例如，在图5描述的示例处理情形中，步骤S505和S506可以在步骤S504之前执行，或并行执行；步骤S507和S508可以在步骤S505和S506之前执行，或并行执行，等等。
下面参考图9(a)和9(b)描述根据本公开实施例的图片管理设备。图9(a)示出了根据本公开一个实施例的图片管理设备900a的示例性结构框图。 该图片管理设备900a可以作为例如图1中所示的终端设备101或102工作，其中要进行图片管理的原始图片初始存储在终端设备101中，而终端设备102中初始未存储所述原始图片。
如图9(a)所示，该图片管理设备900a可以包括标签接收部件910和管理部件911，所述各个部件可分别执行上文中结合图2描述的图片管理方法200的各个步骤/功能。因此，以下仅对该图片管理设备900a的各部件的主要功能进行描述，而省略以上已经描述过的细节内容。
标签接收部件910配置为接收服务端设备基于接收到的原始图片特征进行图像分析而生成的图片标签。原始图片特征是原始图片本身或者是原始图片参数。原始图片参数是与原始图片有关的、并且可以用来进行图像分析的任何适当的参数，例如其可以是需要组织管理的原始图片的压缩编码、或原始图片的图像特征、或其组合。原始图片的图像特征是现有的图像处理领域中可以用来对图像进行分析的特征，例如梯度直方图(HOG)、尺度不变特征变换(SIFT)、深度网络的特征层等。针对接收到的原始图片特征，服务端设备对其进行诸如人脸检测/识别、文字检测/识别、物体检测/识别、场景识别等各种适当的图像分析以生成反映图片内容的图片标签。
管理部件911配置为根据所述图片标签对所述原始图片特征所表征的原始图片进行分类归档。图片标签是基于原始图片特征而生成，而原始图片特征则是能够表征原始图片的压缩编码和/或图像特征、或原始图片本身。因此，管理部件911可以基于由标签接收部件910接收到的图片标签对原始图片特征所表征的原始图片进行分类归档、索引建立等各种图片管理。
该图片管理设备900a能够基于图片内容对原始图片进行分类归档、索引建立等，进而使得用户可以根据图片内容来查询图片，从而使得查询更加高效和人性化。另一方面，由于图片标签并不是在该图片管理设备900a本地生成，而是由服务端设备通过图像处理来生成，因此该图片管理设备900a不需要耗费大量的资源进行大量的数据计算。
在所述图片管理设备900a作为图1中的终端设备101工作时，作为一个示例，所述原始图片特征是原始图片参数，该设备900a可以进一步包括：发送部件，配置为将原始图片发送至服务端设备。作为另一个示例，所述原始图片特征是原始图片参数，该设备900a可以进一步包括：密钥生成部件，配 置为生成与终端设备绑定的唯一密钥；加密部件，配置为利用该唯一密钥对原始图片进行加密；发送部件，配置为将加密的原始图片发送至服务端设备。
在所述图片管理设备900a作为图1中的终端设备102工作时，作为一个示例，该设备900a可以进一步包括：图片接收部件，配置为接收服务端设备从不同于该图片管理设备的另一终端设备接收到的原始图片。作为另一个示例，所述原始图片特征是原始图片参数，该设备900a可以进一步包括：图片接收部件，配置为接收服务端设备从不同于该图片管理设备的另一终端设备接收的加密的原始图片；密钥接收部件，配置为从不同于服务端设备的另一设备接收对原始图片进行加密的唯一密钥；解密部件，配置为利用该唯一密钥对加密后的原始图片进行解密以得到原始图片。在该另一个示例中，所述密钥接收部件可以配置为从所述另一终端设备接收该唯一密钥；或者，从另一服务端设备接收从所述另一终端设备发送至该另一服务端设备的该唯一密钥。
图9(b)示出了根据本公开另一个实施例的图片管理设备900b的示例性结构框图。该图片管理设备900b可以作为例如图1中所示的服务端设备103工作。如图9(b)所示，该图片管理设备900b可以包括接收部件920，标签生成部件921和管理部件922，所述各个部件可分别执行上文中结合图4描述的图片管理方法400的各个步骤/功能。因此，以下仅对该图片管理设备900b的各部件的主要功能进行描述，而省略以上已经描述过的细节内容。
接收部件920配置为接收原始图片特征和加密的原始图片，所述原始图片特征是原始图片本身或原始图片参数。该原始图片特征和加密的原始图片可以来自于存储有大量的原始图片、并希望在服务端设备上进行图片备份的客户端设备。
标签生成部件921配置为对接收到的原始图片特征进行图像分析以生成图片标签，并在生成所述图片标签后丢弃该原始图片特征。针对接收部件920接收到的原始图片特征，标签生成部件921对其进行诸如人脸检测和识别、文字检测和识别、物体检测和识别、图片场景识别等各种适当的图像分析以生成反映图片内容的图片标签。随后，在生成图片标签后，该标签生成部件主动丢弃所述原始图片特征。
管理部件922配置为根据所述图片标签对所述原始图片特征所表征的加 密的原始图片分类归档。图片标签是基于原始图片特征而生成，而原始图片特征则是能够表征原始图片的压缩编码和/或图像特征、或原始图片本身。因此，在通过标签生成部件921生成反映图片内容的图片标签后，管理部件922可以基于该图片标签对通过接收部件920接收到的加密的原始图片进行分类归档、索引建立等各种图片管理。
需要说明的是，在不要求图片数据的安全性时，作为一种替换，接收部件920也可以接收原始图片本身，而不是加密的原始图片，并且相应地管理部件922根据图片标签对原始图片分类归档。按照该替换实现方式，图片管理设备900b同样可以基于图片内容对图片进行分类归档、索引建立等，从而使得可以根据图片内容来查询图片。
图10示出了根据本公开实施例的图片同步设备1000的示例性结构框图。该图片同步设备1000可以作为例如图1中所示的终端设备101或102工作。为了便于说明，在本实施例中，以图片同步设备1000作为终端设备102工作、从而同步得到终端设备101中的原始图片为例进行说明，反之亦然。
如图10所示，该图片同步设备1000可以包括下载部件1001，密钥接收部件1002和解密部件1003，所述各个部件可分别执行上文中结合图8描述的图片同步方法800的各个步骤/功能。因此，以下仅对该图片同步设备1000的各部件的主要功能进行描述，而省略以上已经描述过的细节内容。
下载部件1001配置为从服务端设备下载由另一终端设备生成并上传至该服务端设备的加密的原始图片。所述另一终端设备是存储有要被同步的原始图片的设备，其可以例如通过如下处理生成加密的原始图片并上传至服务端设备：生成与该另一终端设备绑定的唯一密钥；利用该唯一密钥对原始图片进行加密；将加密的原始图片发送至服务端设备。
密钥接收部件1002配置为从不同于服务端设备的设备接收加密原始图片时所采用的唯一密钥。作为示例，不同于服务端设备的设备可以是生成所述密钥的所述另一终端设备。则在该示例中，密钥接收部件1002通过例如P2P传输、蓝牙等无备份网络传输方式从该另一终端设备接收所述密钥。作为另一示例，不同于服务端设备的设备可以是生成密钥的所述另一终端设备预先将密钥发送到其中的另一服务端设备。则在该示例中，密钥接收部件1002在该另一服务端设备上进行身份验证，并且在通过身份验证后，从该另一服 务端设备得到所述密钥。
解密部件1003配置为利用由密钥接收部件1001接收到的唯一密钥对通过下载部件1002下载的加密的原始图片进行解密，以得到原始图片。
